ThisT hope will undeceive thole, who believe that Men sontctimes fpitout the Bleod- Vcstels of their Lungs.

VIII. I cut out the Hearts oftwo Urchines , and found the Systole and ne MotionesDiastole to continue füll two Hours, while the Hearts lay upon aglased h f r ‘yb Mr -Earthen white Piate in a cold Wmdow. The distance of their Diastoles S?

was unequal in time, but very large for half an Hour, and then senliblydiminilhing untill they ceased at the two Hours Distance ; and would notthen be reinforced by-a Needle's Point, which fbr the half Hour preceedingthey would answer at any time. Aster they had ceased above \ of anHour; sb as a Needle prickingthem caused no motion ; yet upon letting:the Piate upon the Hearth in the Chimney, in about two Min. of timethey began to beat, though but weakly; and upon 8 Mtn. continuancethey beat freely; and when removed into the Window again continuedtheir Pullation, without Pricking, above an Hour, and might have donelonger, coulcf I have fpared my Servant to attend them longer. Perad-venture we may hence Conjecture at the Caule of Life and Deatb ; Butwhen (hall we lay any Animal or Insect is Dedd, if it hath Motion ?

IX. i. We latefy met with a Body, which being opened, the Liquor which isr frange peri-

eontained in the Pericardium, or the Bag of theHeart, was found congealed de Murrei b %.into a confistence fit to be cut with a Knife, and j x Iquare Fingers thick f-about the Hearr.

2. I nOftob. 1684. A preternatural' Lump of Fteßi was taken out of an. f GUnduitfeOx at Oxford. The Weight of the whole Substance, cleared from the lit- btttntntbsn“*rrtle Far, &c. adjbyning to it, amounted to 19% l. It very much resem -«»dPericardiumbled a Heart : but it was something stattet, and each of the flat fides fss 7 °^made an Equilateral Triangle. The Basts of this Cone of Flesti was 2 Ft.

7 Inches in Circumference, and a Thread drawn round it length-ways frontthe Basts to the Vertex , came to 2 Ft, 9. In.

When we had divided it, cutting from the Vertex to the Basts of theGene, and passing through both the Ventricles, and Mucro of the Heart ,we found the Heart not to exceed theNatural Size: that which was ex-fraordinary about it, being a large Glandulose Substance compassmg theHeart (unlefi where the Vestels had their paflkge), and stretching ihe Peri-cardium to the excels befbre mentioned. Welaw no Liquor in the Peri-cardium, nor indeed was there room for any; this Glauduhfe Substancetaking up ali the fpace between the Heart and Pericardium, to both whichit grew very fast. It was thickest about the Basts of the Heart , where it«overed the Auricula, and was 3 J Inches thick; It grew thinner on bothsides gradually toward the Mucro , where it was 1 \ Inch thick. In theSeptum Cordis a gritty Sabulose Substance was found, half as big again asa Walnut. In the Lungs were severa! Cystides, conraining Matter more orless Fluid: One very large Cystis held lome Ounces of a Matter not unlikethat of a Steatoma.
